and 10) is provided with a radial guideway 19 in whi chis mounted aslide 20 adjustable by means of a screw 21. A pin 22 carrying a block ordriver 23 freely slidable within a longitudinal guideway 24 in the link.3 is provided on the slide at one end thereof.

The link is pivoted at its lower end to the bed at 25 and at its upperend at 26 to a block 26 adjustably secured to the table. The screw 21 isjournaled at one end 111 a bearing 27 and a bevel gear 28 thereonadjacent the bearing meshes with a' bevel gear the throw of the link 3and the reciprocation of the table.-

An indexing dial 34 is provided for indi-' cating the amount of rotativemovement given to the hand wheel 33 and the position of the block 23. Inadjusting the block 23 from zero to maximum, the shaft 30 must be givenseveral rotations. In order to properly record these rotations, theindexing dial 34 is adapted to be rotated from the shaft 30 at a greatlyreduced speed through thefollowing mechanismz An internal gear 35 issecured to the drum 13 and aneXterna-l gear 36 is freely mountedeccentrically of the shaft 30 onaneccentric portion 32 of the sleeve 32'and connected to the'dial 34 by means of a screw 37. The internal gear35 has 'a greater number of teeth than the external gear 36. The gears35 and 36 are al ways in mesh and as the sleeve 32 is rotated, themeshing position'of these gears travels around the shaft 30. It will beseen that for each such rotation, the dial 34 is rotated rel ative tothe gear 35 the distance of the dif ference of the number of teeth ongears 35 and 36. Thedial may be marked to clearly indicate the effect ofany adjustment of the hand. wheel on the table stroke, This mechanismforms a part of the subject matter of a copending applicationhereinafterspecified.

The slide 20is bifurcated at one end, providing two legs 20 and 20fitting in grooves 19 and 19 on opposite sides of the guideway 19 (Figs.9 and 10). A wedge block 38 having inclined sides 33 and 33 engagingcomplemental surfaces within the bifurcated portion of the slide isadapted to be forced inwardly of the slide to wedge the legs 20 and 20thereof into tight clamping engagejment with the drum. As illustrated;the

block 38 entirely surrounds the screw 21, although, as will beunderstood, such construction is not essential to a realization of theinvention. The means for forcing the block into clamping'engagementcomprises a shaft 39 preferably integral with the block and extendingthrough the tubular shaft 30. A nut 40 is threaded to the end of shaft39 and has bearing against the sleeve 32 which at its inner end bearsdirectly against the drum.

After adjustment of the slide 20 by means of the hand wheel 33, theformer may be tightly clamped in adjusted position by tightening the nut40. It should be noted that the means for operating the parts justdescribed is remote from the parts themselves and is readilyaccessible,it being only necessary for the operator to swing open thepivoted cover member41. this stroke adjusting mechanism just de I do notclaim scribed as a part of my invention, the same"v being the inventionof Herbert .S. Fullerton and comprising the subject matter of a'copending application, Serial No. 436,964, filed January 13,1921.

As the table is recipr'ocated through the oscillatory movement of thelink 3, it will be noted that the distance betweenthe pivots 25 and-26?is different for different positions of the table and such distance isconstantly changing as the table is being reciprocated. To compensatefor this difference, I preferably make the linkin two relative slidingparts, one telescopically mounted for free sliding movement within theother. as illustrated in Figs. 1 and 2 the outerlower .part 3 of thelink is pivoted at 25 and the upper inner part 3*" is pivoted at 26.

justing blocks 42 and 43 are provided in the I guideways in the part 3of the link for taking up lost motion and looseness caused by wear orotherwise. I

It is often desirable and necessary to adjust the operating position ofthe table on the bed and for this purpose, I provide the followingimproved mechanism.v The block 26 is mounted in a dove-tailed recess 44eX- .tending lengthwise of the table at the under sidethereof (Figs. 1,2, 3, 5 and6). A screw 45 journaledv at one end 46 in thetable end hasthreaded engagement with the block -whereby the position of the blockwithin the table recess may be adjusted. The block has a portion thereofcut away toform a recess: within which is mounted a wedge bloc-k4?having a straight side 47 engaging. one'wall of the table recess and aninclined. or tapered rotating the shaft50 the wedgeblock 47 may be movedin one direction or the. other to clamp the block 26 tightly within therecess 44 or to unclamp the same.
